This feels like a scam to me. You can get Satellaviews for cheaper. The price increase is just for the digital data. That is not worth $550, given a number of factors. One, it's just a short visual novel. Two, the game was translated and made workable by emulators years ago, and it is freely distributed around the internet.
Maybe it's hard to put the game onto a flash pak, but does that work, that service, increase the resale value of this worth $550? I can't dictate what fans pay for what, but I wouldn't pay it. But if they can actually convince Chrono fans that this is an essential collectible, they'll gouge them for all they're worth.
I know some purists want to be able to play everything on their tv in the real system with the real controller, but this isn't even a game really. It's a short story. You don't get anything special out of playing it on your tv with a controller, even if you could read Japanese.
Data is identical to all other copies of the same data. It's not unique, not valuable. Tangible things that were made in a factory and come in limited authentic numbers, like real game paks, those we can put a value on. You cannot make an identical, authentic copy of a cart.
